While I understand this, I still have an impression that sometimes not
even lawyers agree. I remember Mozilla re-licencing LPPL files into
some tri-licence to make them compatible/distributable with Firefox
and the LaTeX people (the experts for licencing TeX) arguing that
according to their understanding of the LPPL licence, this shouldn't
be permitted. Go figure.

OK, I can put "license Restrictive/Distributable" to the Portfile
then. Just a question. I see that some ports, for example
textproc/canna, add a few clauses to the license:
license Restrictive/Distributable BSD-old GPL-2+ MIT
Does that mean that one could use
license Restrictive/Distributable Geant4
or is this not desirable? I really don't know anything about the
policy of what needs to be put to the license field in MacPorts (what
MacPorts expect there).
Thank you,
